I have a Sachs 3.2 that I bought and used about 30 years ago, a great engine. I put it to use this past year but found needed carb rebuild, which I did. Now ready to go but found I have no spark. It uses a CD electronic ignition system but not getting any spark now. Any ideas or anyone have one to sell. This is an old system made by CH Electronics Inc.

You might call up CH and see if they have any troubleshooting tips. Also if it is that old make sure all the electrical connections are clean. I had one with a poor connection from the magnetic trigger to the ignition box. a little electrical cleaner and plugging/unplugging a few times did the trick.
